Abstract:
Four new hybrid chloroantimonates(III) and chlorobismuthates(III) with halogen bond-linked I2, (H2bpe){[MCl5](I2)} (M = Sb(III) (1); M = Bi(III) (2); bpe = 1,2-bis(4-pyridil)ethane) and (H2bpp){[MCl5](I2)} (M = Sb(III) (3); M = Bi(III) (4); bpp = 1,3-bis(4-pyridil)propane), were synthesized via a reaction between Sb2O3/Bi2O3, I2 and the corresponding bis(pyridines) in HCl. Despite sharing the same formulae of supramolecular anionic parts, they showed significant structural diversity, revealing three different structural types. Features of the halogen bond in 1-4 were examined via theoretical methods.

Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
